Successful Boiler Hydrostatic Test for the High-Oil-Rich Naphthenic Oil Project Author/Source: Sinochem News Network Date: August 12, 2019 Clicks: 51 On August 9, the hydrostatic test of the 2 x 75t/h boilers in the power station of the **key energy development project – the second phase of Shenmu High-Oil-Rich Energy Technology Co., Ltd.’s project for producing naphthenic oil through the hydrogenation of coal tar across its entire fraction range, was successful on the first attempt, marking theほぼ complete installation of the boiler equipment. It is reported that the 2 x 75t/h boilers in this project are coal-fired circulating fluidized bed boilers of medium temperature and medium pressure, with a single drum, natural circulation, and a “π”-shaped arrangement. To ensure the success of the boiler hydrostatic test on the first attempt, the company held a special meeting with China National Chemical Engineering Corporation Sixth Construction Company to develop a detailed plan for the hydrostatic test, as well as on-site safety and emergency measures and risk prevention strategies. The pressure for the boiler hydrostatic test is 4.2 MPa, and the overpressure test pressure is 5.5 MPa. After reaching the test pressure, the pressure was maintained for 20 minutes; during this time, none of the welds showed any leakage, and all technical specifications met the design requirements. The pressure-bearing components exhibited no cracks, deformation, or leaks. Staff from the Yulin Special Inspection Institute confirmed on-site that the system was safe and reliable, marking the successful completion of the hydrostatic test. (Li Hua, Chang Cheng)
